Ottima pietra, ottima abrasione, ma prezzo un po elevato, cmq la consiglio

So, my first Blackstone had a big chip out of it from shipping, so I had to return it and order a replacement. Once I got it on my T-8 it soaked up as much water as the original stone, so be aware of that and keep an eye on the water level when you first start to use it. It ran perfectly true with no wobble and was also perfectly round. In comparison to to the original stone that came with the machine it does work much faster and leaves a very fine edge on the blade that requires minimal honing. I haven't noticed that the stone wears any faster than the original stone as other have stated in their reviews. It's only about $30.00 more expensive than the original stone and I'll say that it performs much better. I don't need to push anywhere near as hard on the blade and it's nice that my time spent grinding is about cut in less than half.I now use the original stone for outdoor tools and hunting knives and use the Blackstone for my automatic and kitchen knives with the more expensive blades and more exotic (harder) steel alloys. I feel that the Blackstone gives me greater control over the process and gives better results on the more expensive knives.

J’étais septique quant à l’achat de cette meule vu son prix mais j’en suis satisfait. La meule est parfaite pour rattraper une lame. Elle grignote plus vite que la meule de base. J’ai testé également une lame céramique dessus et cela fonctionne. Bref satisfait de l’achat.

Excellent product, best price yet and fast shipping
